rovements in BottleCaps, of which the fol'I owing is a specification.

The invention relates to an im rovement bottle caps' arranged for inter ocking enga ement wlth the bead of a bottle neck.

he m-ain'object of the present invention lockingjflanges adapted to engage beneath .thebead ofthe`bottle, thenorm'al disposil tion-of said flanges being at an angle tothe line of strain against the cap when in-sealing position; whereby to utilize the maximum resistance tosuch strain.

Another obj ect of the invention is vision of a vcap formed of a single blank, and

clam ing in sealing positionv on the bottle mout .a simple means being provided whereby the cap may be rearranged in sealing positionlafter removal to permit access j to the contents of the bottle.

The invention Ji/'illA be described in the following speciiication, reference being had particularlyto the accompanying drawings, 111 whichz- Figure 1- isa transverse vertical sectional view showing the preferred form of cap inapplied position. ig. 2 is a side elevation o the same viewed at right angles to the line -of section of Fig. 1. Fig. 3 is a similar view,

viewed at right angles to Fig. 2. Fig. 4- is a plan of the c'ap applied. Fig. 5 is a plan of the initiall formed blank on a scale some-v what sma erthanl shown'iny Fi 4. Fig. 6 is a Abl'okerrvertical section i lastra-tin a slightly modified form of cep in app 'ed position. Fig. 7 isa view in si e elevation of the same, taken at ri ht angles to the line of section ot Fig. 6. i 8 is 'the initially formed blank of the mo ed cap.

Referri particularly to Figs. 1 to 5 inclusive, wherein is clearly illustrated the specific construction and mode of application of the preferred` form of my improved cap, it will be noted thatsaid cap-is cut or stamped from a rior diameter of the bottle mouth with which as will be evident.

" the `capisadapted to coperate, the side edges of the blank 2 projecting from said median line in a forwardly 'and outwardly inclined direction, the free ends. of the blank being curved at 3, .as shown.

Along the longitudinal median line, the blank-1 is formed in the edges 3 with a semicylindl'ical notch 4, andbetween said notches and the transverse center ofthe blank, lform the .blank withf openings 5, preferably disposeda is the production of a bottle cap `formed with eater distance from the transverse median'lineof the blank than from the proximate notches 4.. The blank is folded or bent along the dotted lines 6 adjacent to each edge A 3, thebentportion being projected u ward at f an angle from the body ofthe bla videylockingfflanges 7. 'The blank lis then formed 'into cap shape, providing the disk ,the pro-' v to proortion 8, and side flanges 9, it being noted t om Fig. 2 ofthe drawings that owing to the relative formationof the edges 2 of the blank, the flanges 9- are, inthe completed cap separated to provide in effect twodistinct slde flanges, eachless in peri heral length than half the circumference,v o, the bottle mouth.

vAs thus constructed the cap in completed form comprises an imperforate disk of'a size to overlie rthe bottle mouth, from which depende independent side flanges, the4 ,lower edges of the `flanges being formed with in'- wardly vand upwardly inclined locking flanges, as clearly seen in Fig.' 1.

.In use the cap isl a plied to a bottle 10 formed near the, mout thereof with a bead 1 1. 'lhe relatively lower surfaceof the bead is preferably disposed at a right angle to the length of. the neck, thereby providing a squareshould'er 12 at the lower vedge of the bead, "The cap, initially provided with the usual sealing disk 13 ofany desired material, is secured upon the bottle by the application of pressure to the disk 8, the side riding over the Outer surfaceof the bead 11,

plied to the side flanges 9 of t e cap to force Lateral ressure is ap-` anges '9 the locking flanges 7 beneath the shoulder 12 of the bead, thereby securing the cap in place.

When desired to remove the cap any properlly formed: tool or implement may be inserted between the locking flange and the bottle neck, and one or the other of the side flanges ,7 laterally displaced to remove the locking 'flange from beneath the bead, whereupon the .ca mv be slip ed laterally from vthe bottle mduthllr In repiiacin'g the-cap after such displacement, the' implement is introduced.

' cap, insure apro er locking cooperation of the flanges 7 wit side flanges are independently movable and thereby readily accommodate themselves to shekpress'ure necessary to secure 'a proper The .particular feature of the resent invention is the dispositionv oft e locking f langesf?. In locking position said flanges 'Z are yarranged at an u Ward and inward ineline relative to the s1de flan es 9. The resistance of the cap to the dis acing strain is,

therefore, practically lengt wise, or vertically, of the locking flanges 7, thereby requiring practically a crushing of said` lateral flanges before the cap will yield to the displacing strain. v

For use with bottles designed for export trade or for long shipments,l I prefer that the cap be provided with an additional locking means to prevent accidental lateral displacement of either of the locking flanges in andling the bottles. To provide this additional lockin means the ca blankis formed as illustrate in Fig. 8, wherein it will be noted that saidblank is identical with the preferred form with the addition thereto of ears 14 projected from the side edges 2 in the transverse median line of the blank, each of these ears being erforated as at 15.

In the use ofp the modified form of cap, securing wires 16, arranged in pairs, are, prior to the securing of the cap on the bottle as before described, passed across the disk 8 of the cap 'with their-respective ends projected through the openings 15 in the opposing ears 14. The ears are preferably of. a len th to dispose their openin s 15 on a line vwit the locking shoulders oft e bottle'bead when the cap is in place, and the ends of the two wires projecting through each respective .ear are separated and passed around the bottle in opposite directions, bein directed between the locking flan es 7 an the side flanges 9. The termin'as of the wires so projected fromk one ear are passed over the opposing ear and secured by intertwisting, as at 17, Fig. 7. The cap is thus secured to preventthe accidental lateral movement of either side flange, it being noted that the wires rest against the outer surface of the leeg flanges Aand thereby positively prethe shoulder 12, as said vent displacement of the cap under any strain or handling to which the bottles may be subjected.

. In connection with the improved cap Clescribed, I contemplate the use of a particular form of bottle bead, as shown more articularly in Fig. 6. In this form the re atively outer. surface of the bead 18 inclines downwardly and outwardly as at 19, thereby guiding the locking flanges in the application of the cap, and more positively insuring their opieration with the locking shoulder of the It is to be understood that the cap is designed for application to any form of bottle rovided with a bead with which the locking anges may engage, and that the salient feature of the present invention resides in the formation of a bottle ea having independent side flanges, each oFwhich is provided with a locking flange extending upwardly and inwardly at an angle there om, the arran ement being such that the extreme upper or free edge of each locking flange engages directly beneathand' in contact with the locking shoulder of the bead.

While preferring the details of construetion and arrangement of parts shown and described, it is to be understood that various changes and modifications may be resorted to without departing from the spirit of the present invention, that I wish to include, as part of the present invention, all such changes and variatlons as may fall within the scope of the 'appended claims.

Havin thus described the invention, what I c aim is:

1. A bottle cap having a divided side flange, and a locking flange projectin upwardly and inwardly from the lower .erige of each division of the side flange, each division of the side flange being formed with an opening in transverse alinement with the upper edge of the locking flange.'

2. A bottle cap havlng a divided side flange, lockin flanges rojecting from each division of t e side ange, ears disposed between the divisions of the side flange, and auxiliary locking means passed above the cap and through the ears.

3. A bottle cap havi a divided side flange, lockingflanges projecting from each division of the side flan e, ears disposed between the divisions of te side flange, and a plurality of locking wires passed over the cap with their ends projecting through the respeetive ears.

In testimony whereof, I affix my. signature in presence of two witnesses.
